Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559162, here are decompositions:

13 + 31559149 = 31559162
31 + 31559131 = 31559162
199 + 31558963 = 31559162
223 + 31558939 = 31559162
331 + 31558831 = 31559162
373 + 31558789 = 31559162
421 + 31558741 = 31559162
433 + 31558729 = 31559162

Showing the first eight; more decompositions exist.
